Next the variable frequency divider 3 frequency-divides an originating frequency from VCO 1 into fDSS A phase comparator 4 compares an output phase from the divider 3 with an output phase from DDS 2 and controls the originating frequency of VCO 1 so as to minimize the phase error. Then the frequency dividing ratio and the originating frequency fDDS of the divider 3 are controlled by a set value set by a microcomputer. Thereby, a PLL. circuit can remarkably simplify the PLL, circuit and reduce the size and the cost of a device to mount for improving PLL performance by using the output frequency fDDS of DDS.

Title: Forming method for pattern
Inventor: UENO ATSUSHI
IPC: G03F7/20
Filed: 1987-10-20
Abstract: PURPOSE:To form a fine rectangular pattern in which two-dimensional effect due to the diffraction of a light is eliminated by employing two different masks, and exposing the mask patterns of the masks by crossing them. CONSTITUTION:Negative type photosensitive resin is formed on a semiconductor substrate, and exposed with ultraviolet ray with photomasks 100, 200. Linear mask patterns (shielding parts) 101, 201 are exposed in a crossing state, and, in this case, the alignment of the mask patterns may be or may not be performed according to the step. When they are exposed with the masks 100, 200, photosensitive resin 300 is exposed. That is, the pattern of an unexposed part 400 not exposed with the mask patterns 101, 210 is formed on the resin 300. Since the crossing parts are of the mask regions of the linear portions with two different masks, two-dimensional effect is not generated by the diffraction of a light and, since the masks are individually exposed, the deterioration of the shape due to the two-dimensional effect is not generated, thereby obtaining a preferable rectangular pattern.

Filed: 1991-10-14
Abstract: PURPOSE:To efficiently record digital data by preparing plural number of channels for digital data in which one word is formed by a prescribed bit and by recording these data in the number of tracks which exceeds the number of channels. CONSTITUTION:Digital data, which consist of prescribed number of data trains, are optically recorded in the respective digital audio data recording tracks D1 through D3. In this case, each sample data of 16 bits are recorded in a square manner with 4 bits in longitudinal and 4 bits in lateral directions. Therefore, the data error rate caused by defects in the longitudinal direction of a film is reduced to 1/4 compared with the case in which the 16 bit sample data are longitudinally placed in a single track. Furthermore, compared with the case in which the data are laterally recorded over 16 tracks, the data error rate caused by defects in the lateral direction of the film width, is reduced to a minimum.
